Patrick Tims via NaturalHealth365 – The pervasive presence of this toxic substance in everyday items creates a significant health threat. BPA (Bisphenol A), a colorless and soluble chemical, is likely within reach right now, as it’s commonly used in plastics and embedded in so many consumer products. The pervasive presence of this toxic substance in everyday items creates a significant health threat. A recent study in The Journal of Hazardous Materials links early BPA exposure to a higher risk of serious health issues, including type 2 diabetes, obesity, stroke, and heart disease. This early exposure can disrupt hormonal balance, leading to long-term consequences that extend well into adulthood. BPA is found in the most common consumer products BPA is found in food packaging, processed foods, consumer products, and even industrial items, making it nearly impossible to avoid. As an endocrine disruptor, this chemical alters hormones, increasing the risk of chronic diseases over time. Unfortunately, because it’s so widespread, exposure often begins early in life, during those crucial formative years. Research shows that BPA exposure in childhood sets the stage for cardiometabolic health issues that persist into adolescence and adulthood. By damaging blood vessels and the heart, BPA compromises the body’s ability to regulate weight, maintain healthy blood sugar levels, and process nutrients effectively, leading to long-term health challenges. A closer look at the BPA research that’s shaking up the health industry To better understand BPA exposure, the research team used direct and indirect methods to predict its impact. They cross-referenced food consumption diaries with demographic data, urine samples, and blood biomarkers, adjusting for key variables like overall energy intake. Participants were asked to provide detailed information about their food and drink choices, including when and where they consumed them and specifics like preparation methods, portion sizes, brand, and packaging. Because BPA exits the body quickly, 24-hour urine samples were analyzed to more accurately measure daily exposure. The team followed up at 4-, 7-, and 10-year intervals, with a 13-year follow-up for adolescents, to track the long-term effects of early exposure. BPA causes a multitude of health problems most aren’t aware of According to the study, BPA exposure is linked to increased fat mass, particularly around the waist, leading to a higher risk of abdominal obesity. This type of fat accumulation is especially concerning, as it’s associated with a greater risk of metabolic conditions like type 2 diabetes and cardiovascular disease. Additionally, BPA exposure can significantly impact insulin function, raising insulin resistance and levels in the body. This disrupts the body’s ability to regulate blood sugar effectively, which, over time, can lead to chronic conditions such as insulin resistance and type 2 diabetes. The compound’s effects on metabolism can be subtle but serious, impacting long-term health in often overlooked ways. Tips to reduce BPA exposure If you have a child, or teen at home, reducing their exposure to BPA is essential. While BPA is widespread in consumer products, there are simple actions you can take to limit its presence in your home. When shopping, avoid processed foods and choose organic options instead. Once home, transfer food from plastic packaging into BPA-free containers, such as glass or stainless steel. To further reduce BPA exposure, minimize the use of plastics whenever possible. Opt for bulk items instead of those packaged in plastic and choose products with plastic-free packaging. By making these small changes, you can significantly lower your family’s BPA exposure and support healthier long-term outcomes.

Fungus Breaks Down Ocean Plastic

Royal Netherlands Institute for Sea Research via EurekAlert! – A fungus living in the sea can break down the plastic polyethylene, provided it has first been exposed to UV radiation from sunlight. Researchers from, among others, NIOZ published their results in the scientific journal Science of the Total Environment. They expect that many more plastic degrading fungi are living in deeper parts of the ocean. The fungus Parengyodontium album lives together with other marine microbes in thin layers on plastic litter in the ocean. Marine microbiologists from the Royal Netherlands Institute for Sea Research (NIOZ) discovered that the fungus is capable of breaking down particles of the plastic polyethylene (PE), the most abundant of all plastics that have ended up in the ocean. The NIOZ researchers cooperated with colleagues from Utrecht University, the Ocean Cleanup Foundation and research institutes in Paris, Copenhagen and St Gallen, Switzerland. The finding allows the fungus to join a very short list of plastic-degrading marine fungi: only four species have been found to date. A larger number of bacteria was already known to be able to degrade plastic. Follow the degradation process accurately The researchers went to find the plastic degrading microbes in the hotspots of plastic pollution in the North Pacific Ocean. From the plastic litter collected, they isolated the marine fungus by growing it in the laboratory, on special plastics that contain labelled carbon. Vaksmaa: “These so-called 13C isotopes remain traceable in the food chain. It is like a tag that enables us to follow where the carbon goes. We can then trace it in the degradation products.” Vaksmaa is thrilled about the new finding: “What makes this research scientifically outstanding, is that we can quantify the degradation process.” In the laboratory, Vaksmaa and her team observed that the breakdown of PE by P. album occurs at a rate of about 0.05 per cent per day. “Our measurements also showed that the fungus doesn’t use much of the carbon coming from the PE when breaking it down. Most of the PE that P. album uses is converted into carbon dioxide, which the fungus excretes again.” AltThough CO2 is a greenhouse gas, this process is not something that might pose a new problem: the amount released by fungi is the same as the low amount humans release while breathing. Only under the influence of UV The presence of sunlight is essential for the fungus to use PE as an energy source, the researchers found. Vaksmaa: “In the lab, P. album only breaks down PE that has been exposed to UV-light at least for a short period of time. That means that in the ocean, the fungus can only degrade plastic that has been floating near the surface initially,” explains Vaksmaa. “It was already known that UV-light breaks down plastic by itself mechanically, but our results show that it also facilitates the biological plastic breakdown by marine fungi.” Other fungi out there As a large amount of different plastics sink into deeper layers before it is exposed to sunlight, P.album will not be able to break them all down. Vaksmaa expects that there are other, yet unknown, fungi out there that are degrading plastic as well, in deeper parts of the ocean. “Marine fungi can break down complex materials made of carbon. There are numerous amounts of marine fungi, so it is likely that in addition to the four species identified so far, other species also contribute to plastic degradation. There are still many questions about the dynamics of how plastic degradation takes place in deeper layers,” says Vaksmaa. Plastic soup Finding plastic-degrading organisms is urgent. Every year, humans produce more than 400 billion kilograms of plastic, and this is expected to have at least triple by the year 2060. Much of the plastic waste ends up in the sea: from the poles to the tropics, it floats around in surface waters, reaches greater depths at sea and eventually falls down on the seafloor. Lead author Annika Vaksmaa of NIOZ: “Large amounts of plastics end up in subtropical gyres, ring-shaped currents in oceans in which seawater is almost stationary. That means once the plastic has been carried there, it gets trapped there. Some 80 million kilograms of floating plastic have already accumulated in the North Pacific Subtropical Gyre in the Pacific Ocean alone, which is only one of the six large gyres worldwide.” Journal Science of The Total Environment DOI 10.1016/j.scitotenv.2024.172819 To read the original article click here.

Chemicals in Plastic May Contribute to Weight Gain

AHA Publisher — Fri, 28 Jan 2022 08:00:07 +0000

Norwegian University of Science and Technology (NTNU) via Newswise – It may sound strange, but chemicals in plastic may make the bathroom scale a less pleasant place to visit. Every day, we come into contact with plastic products. A lot of plastic is found in food packaging. Plastic packaging is common for practical reasons, because it is cheap and because it can increase a food’s shelf life. But plastic contains thousands of different chemicals. Some of these can affect your metabolism, and thus perhaps also your weight. Found 55 000 Different Chemicals “Our experiments show that ordinary plastic products contain a mix of substances that can be a relevant and underestimated factor behind overweight and obesity,” says Martin Wagner, an associate professor at NTNU’s Department of Biology. A research group looked at 34 different plastic products in the laboratory to see which chemicals they contained. These were everyday products that many people use, like yoghurt containers, drink bottles and kitchen sponges. The researchers found over 55 000 different chemical components in these products and identified 629 of the substances. Eleven of them are known to interfere with our metabolism, called metabolism-disrupting chemicals. For a long time, experts believed that most plastic chemicals would stay in the material. However, Wagner’s team has recently shown that plastic products leach a large number of chemicals under real world conditions, thus enabling them to enter the body. Previous research also suggests that some plastics contain endocrine-disrupting chemicals that may affect our development and fertility. Now it appears that they may contribute to weight gain as well. Contribute to Fat Cell Development Chemicals from one third of the plastic products investigated in the new study were found to contribute to fat cell development in laboratory experiments. The substances in these products reprogramed precursor cells to become fat cells that proliferated more and accumulated more fat. While some plastic products contained known metabolism-disrupting substances, others did not but nevertheless induced the development of fat cells. This means that plastics contain currently unidentified chemicals that interfere with how our body stores fat. “It’s very likely that it is not the usual suspects, such as Bisphenol A, causing these metabolic disturbances. This means that other plastic chemicals than the ones we already know could be contributing to overweight and obesity,” says Johannes Völker, the first author of the study who is affiliated with NTNU’s Department of Biology. Major Societal Problem Overweight and obesity contribute to some of the most common causes of death in the world, such as cardiovascular disease and cancer. They can also increase our susceptibility to various infections, such as the effects of COVID-19. Around two billion people in the world are overweight, and the problem is growing. Approximately 650 million of these fall into the obese category. The reasons for this are of course complex, but plastic chemicals may well be a factor that we have not previously considered. These chemicals include phthalates and bisphenols, but the new study shows that there are many more substances that trigger these problematic effects. The results of the latest study have been published in Environmental Science & Technology. The researchers came mainly from NTNU, with contributing partners from Goethe University in Frankfurt am Main, Germany. To read the original article click here.

Chemicals Found in Everyday Products Found to Be Harmful to Fertility

University at Albany, State University of New York via Newswise – ALBANY, N.Y. (Nov. 1, 2021) – Three studies led by a University at Albany PhD student found that a group of chemicals found in many plastic products are harmful to women who are pregnant and to couples planning a pregnancy – yet the products are often not on the list of things to be avoided. Phthalates — a group of chemicals used to make plastic more flexible, found in items ranging from toys to personal care items and flooring — have long been thought to be associated with infertility but the results have been inconsistent, explained Thoin F. Begum, an environmental health sciences PhD student who led the recent studies. “Phthalates are known to be disruptors to the endocrine system, but the extent and exact outcomes of the exposure is still relatively unknown,” Begum said. “Animal studies have shown that phthalates are reproductive toxicants, so we wanted to determine if phthalates are linked to any reproductive outcomes in humans.” In three separate studies, published in the International Journal of Hygiene and Environmental Health, Reproductive Toxicology and Reviews on Environmental Health, Thoin and colleagues found that several of the environmental chemicals are indeed harmful to the reproductive process and can have harmful effects on the fetus. In one of the studies, the team enrolled over 30 couples visiting a fertility clinic in San Francisco to examine their lifestyle and behavioral patterns, and collected urine samples to determine how much and what types of environmental chemicals they were exposed to. The analysis showed that women who applied several lotions, moisturizers and other personal care products had more exposure to lower molecular weight phthalates, while women who applied nail polish and perfume had more high molecular weight phthalates in their bodies. The male partners of the women who used of lotions and moisturizers also were associated with high molecular weight phthalates, indicating that both women and men face exposure to phthalates through the use of personal care products. When they looked at both partners’ phthalate exposure, the researchers found that greater exposure to the phthalates specific to personal care products (MBP, MHxP and MEHP) were associated with lower likelihoods of a successful pregnancy and live birth. Additionally, the male partner’s exposure to phthalates also mattered when considering the likelihood of conception and having a live baby — suggesting that when thinking about becoming pregnant, both partners should be aware that using personal care products may lead to unwanted exposure to phthalates. “Pregnant women and those planning a pregnancy, including the woman’s partner, should limit their exposure to these chemicals by not using products such as nail polish and perfume, cologne, hair dyes and a slew of other personal care products,” Begum said. “Interestingly enough, and of concern, these things are often not on the list provided by doctors of things couples should avoid during a pregnancy or while planning one.” Begum worked with associate professors Beth Feingold and Xiaobo Romeiko, professor David Carpenter, as well as fellow student Celeste Butts and Michael Bloom, Begum’s MS advisor who is currently at George Mason University. Colleagues at University of California at San Francisco also participated in the research. Though the three peer-reviewed studies indicated that phthalates are a reproductive toxicant, Begum noted that more research on phthalates overall is needed. “While it is quite clear that phthalates are reproductive toxicants, the other effects are a bit unclear,” she noted. “Phthalates appear to be thyroid antagonists in that they reduce thyroid hormone levels with multigenerational and persistent effects. In our review, we found that exposure to phthalates may be associated with a wide range of other health outcomes aside from reproductive outcomes and this requires further research.” To read the original article click here.
